The victim said Lopez started an argument May 9, pulled her around the apartment by her hair, then kicked and punched her in the head and stomach. She was 38 weeks pregnant at the time.

Lopez was arrested but hasn't shown up for court. He was convicted of beating up the same victim two years ago. When he was being arrested, he fought with officers, said he had an assault rife, kicked the cruiser's windows and partition, called the officers racist names and said they should be killed.
